Multiple Choice
In meiosis I, what is the primary event that occurs during telophase I?
A
Chromosomes condense and the nuclear envelope breaks down while the spindle begins to form.
B
Homologous chromosomes arrive at opposite poles, nuclei may reform, and cytokinesis produces two haploid cells whose chromosomes are still composed of sister chromatids.
C
Homologous chromosomes pair (synapsis) and crossing over occurs between non-sister chromatids.
D
Sister chromatids separate and move to opposite poles, producing four haploid cells.
Verified step by step guidance1
Identify the phase in question: Telophase I is the final stage of meiosis I, following anaphase I.
Recall the key events of meiosis I: During meiosis I, homologous chromosomes are separated, reducing the chromosome number by half.
Understand what happens specifically in telophase I: Homologous chromosomes reach opposite poles of the cell.
Note the cellular changes: The nuclear envelope may reform around each set of chromosomes, and cytokinesis (division of the cytoplasm) occurs, resulting in two haploid cells.
Remember the chromosome composition: Each chromosome still consists of two sister chromatids, as they have not yet separated (this occurs in meiosis II).
